  1. AKI stages were defined using the kidney disease improving global outcomes (KDIGO) criteria. CCI: Charlson comorbidity index; MBP: mean blood pressure; PCO2: partial pressure of carbon dioxide; RBC: red blood cell; RDW: red blood cell volume distribution width; BUN: blood Urea nitrogen; INR: international normalized ratio; ALP: alkaline phosphatase; ALT: Alanine transaminase; AST: aspartate aminotransferase.
